4 Claims. (01.. 81-192) In forming pipe cutters the common practice edsocket 20. The end of this plate engages the heretofore has been to form the guide body and guide portion l of the body ,andwith' the guiding hook end together. assemble the sliding block surface l6 completes the guiding surfaces of thereon, and then secure the nut end of the the block along the inner edge of the guide porbody.: In this way the guide block could be tion of the body. The screw 1 has a head 2| 5 readily assembled on the guide portion of the which extends into a socket 22 in the block. The body and the guide portion of the body'readily plate l8 engagesthe rear of the head 2| and machined. looks it in the socket 22. I

With the present invention the body and the In machining the cutter the two sides of the I hook and nut endsare'formed integrally, preferbody are flat surfaced. The edges of the'guide l0 ably of a forging. The block has a guide open are machined. The opening through the block I ing through it with integral surrounding walls so which is preferably solid is broached and the formed that it can be assembled over the hook guide plate completes a perfect fitting guide surend and after the assembly the walls of the openface for the block so that a perfect sliding fit is ing are supplemented by a plate which completes made on the guide portion of the body. v '15 the guiding surfaces and secures. the usualscrew This structure permits of the use of a simple to the sliding block. In this way'a more rugged forging for the body giving greater strength and tool may be provided than tools made up of sevlightness to the tool and in some respects simeral parts and also can be economically produced. plifying the manufacture.
